In fact I can make a better arguement it is tougher to get to the SuperBowl from the AFC..
Since 2002 the Patriots have reached the SB 5 times, Steelers 3 times, Colts 2 times and Raiders 1 time.. So if you take out the Colts which Peyton played for, then only 3 teams (dominated by 2) have reached the SB in the past 11 years..
In the NFC on the flip side: AZ 1 time, Seattle 1, Giants 2, Tampa Bay 1, Packers 1, Saints 1, Panthers 1, Eagles 1, Bears 1 and Rams 1.. The NFC has not been dominated by a few teams as the AFC is..
If Peyton was to come to AZ, youd have to think we would be a team that can contend every year..
